Noone needs all of them, but since we're not the overall fastest cracker on earth, we might aim for being the most versatile. And I think we are.

When I do a full --test, I want to test all formats. In bleeding, there is limited wildcard and class support since some time, for example:

../run/john -test -format:cpu
../run/john -t -form:gpu
../run/john -t -form:cuda
../run/john -t -form:opencl
../run/john -t -form:dynamic
../run/john -t -form:hmac-*
../run/john -t -form:krb5*

BTW, this can be used together with eg. --list:

$ ../run/john --list=format-details -format:hmac-*
hmac-sha224	125	1	1	00020003	2	32/64 OpenSSL	HMAC SHA-224		28	64
hmac-sha256	125	1	1	00020003	3	32/64 OpenSSL	HMAC SHA-256		32	64
hmac-sha384	125	1	1	00020003	2	64/64 OpenSSL	HMAC SHA-384		48	128
hmac-sha512	125	1	1	00020003	3	64/64 OpenSSL	HMAC SHA-512		64	128
hmac-md5	125	12	12	00020003	6	128/128 SSE2 intrinsics 12x	HMAC MD5		0	16	768
hmac-sha1	125	4	4	00020003	4	128/128 SSE2 intrinsics 4x	HMAC SHA-1		0	20	256

...or why not:
$ ../run/john -format:gpu hashfile

We could add support for leading wildcard too, like -format:*sha256. I saw no need for it at the time.
